Cable trays are mainly made of steel,aluminum alloy,and fiberglass.The surface treatment of steel bridge accessories can be divided into processes such as painting,spraying,electroplating,hot-dip galvanizing,powder electrostatic spraying,etc.The installation of bus duct phase separation blocks mainly involves installing along the top plate.Install horizontally and vertically along the wall,along the vertical shaft,and along the ground.Installation along cable trenches and pipeline supports,etc.The support(hanger)used for installation can be selected from finished products or self-made.The main ways to fix the support(suspension)frame include welding on pre embedded iron parts and fixing with expansion bolts.

　　The connector for bus duct includes two joint side connecting plates,an insulation partition group,and insulation bolts.The two joint side connecting plates are equipped with insulation partition groups parallel to the joint side connecting plates.The insulation partition group includes two insulation outer partitions and multiple inner partitions.Multiple insulation inner partitions are arranged parallel to each other between the two insulation outer partitions.There is an insulation bolt fixing hole at the corresponding position on the two joint side connecting plates,as well as on the two insulation outer partitions and multiple inner partitions.The insulation bolt is an insulation fixed torque bolt,which passes through the bolt fixing holes on the joint side connecting plates,insulation outer partitions,and multiple inner partitions and is connected to the two joint side connecting plates.Upper insulation fixation,between the joint side connecting plate and the insulation outer partition,between the insulation outer partition and the insulation inner partition And there is an insulation sleeve insulation connection between adjacent insulation partitions,with the insulation sleeve on the fixed torque bolt rod at the corresponding position.

　　The main components of the protective cover and connecting parts are ladder type,tray type,and trough type bridge accessories,which include width adjustment pieces,height adjustment pieces,connecting pieces,angle adjustment pieces,partition protective covers,etc.It is a necessary accessory for cable tray installation,including widening,raising,connecting,small angle turning in horizontal and vertical directions,and separating power and control cables.Bridge accessories are a very important part of cable trays.In this case,the requirements for it are very strict because it needs to be applied to some important fields.It mainly includes various cable,conduit cable clamps,connections,fastening bolts and other bridge accessories.All connections,fastening bolts and cable clamps are galvanized.Other groove plates and perforated angle iron surface treatments include electrostatic spraying,galvanizing,and painting.

　　Different product models may have different effects when used,so choosing based on actual requirements can promote better protection.Of course,in the selection process of busbar trunking phase separation blocks,it should be determined according to the actual situation of the power supply and distribution lines,so as to play a greater role in use.Of course,when choosing products,we still need to pay more attention,as better products are more recognized and can play a greater role in reliability.
